Invalid Native checksum on NETMF.System

I cannot debug after installing the beta because the following error appears in the output window:

I uninstalled the old NETMF installation before installing the beta, and I removed and re-added all of my references just to make sure my project wasn’t still referencing an old version to no avail.

You have assembly/firmware mismatch

As always, update your firmware and start with NEW project.

Once it is working then go back and try old project …which you need to remove all GHI assemblies and then put them back.

D’oh!

Sorry about that!
